模拟一个万花筒,鼠标点击可以变换图形
python
import pygame
import sys
import math
import random
pygame.init()
# 设置窗口大小
WIDTH, HEIGHT = 800, 600
CENTER = (WIDTH // 2, HEIGHT // 2)
# 设置颜色
BLACK = (0, 0, 0)
# 初始化屏幕
screen = pygame.display.set_mode((WIDTH, HEIGHT))
pygame.display.set_caption("Kaleidoscope")
clock = pygame.time.Clock()
def generate_random_color():
return random.randint(0, 255), random.randint(0, 255), random.randint(0, 255)
def draw_kaleidoscope():
num_slices = 12
angle_increment = 360 / num_slices
for i in range(num_slices):
draw_pattern(i * angle_increment)
def draw_pattern(rotation_angle):
num_lines = 100
line_length = 200
angle_increment = 360 / num_lines
for i in range(num_lines):
angle = math.radians(i * angle_increment)
x1 = int(CENTER[0] + line_length * math.cos(angle))
y1 = int(CENTER[1] + line_length * math.sin(angle))
rotated_x1 = int(CENTER[0] + (x1 - CENTER[0]) * math.cos(math.radians(rotation_angle)) -
(y1 - CENTER[1]) * math.sin(math.radians(rotation_angle)))
rotated_y1 = int(CENTER[1] + (x1 - CENTER[0]) * math.sin(math.radians(rotation_angle)) +
(y1 - CENTER[1]) * math.cos(math.radians(rotation_angle)))
pygame.draw.line(screen, generate_random_color(), (rotated_x1, rotated_y1), (x1, y1), 2)
running = True
draw_kaleidoscope()
while running:
for event in pygame.event.get():
if event.type == pygame.QUIT:
running = False
elif event.type == pygame.MOUSEBUTTONDOWN:
screen.fill(BLACK)
draw_kaleidoscope()
pygame.display.flip()
pygame.display.flip()
clock.tick(30)
pygame.quit()
sys.exit()
结果:
改进:
改变算法 ,让万花筒的表现更绚丽多姿 。
